I am so happy to have finally found that!
Rimmel's Lasting Finish Foundation in Shade 100 Ivory. I was afraid it would be too orange for me or oxidize like other pale shades do. I was happily proven wrong.
$9. It claims to be sweat, heat, and humidity proof for up to 25 hours.
Pros: No oxidization
Doesn't break me out
Lasts 18 hours
Doesn't last 25 hours
So basically this rocks. Congrats little foundation, you are my new fave! I love you dear thing!
Staying Power: 9/10
Total: 48/50 = A = Pandamonium!!
I love this foundation, it really lasts and gives me a flawless finish!
